U.S. State Department expands travel warnings for Mexico

The U.S. State Department has expanded its travel advisories, warning of dangers in parts of Mexico that hadn’t previously been addressed, including the Caribbean coast.

It’s due to increased violence in the area. The advisory stated that turf battles between criminal groups had resulted in crimes and killings in areas frequented by U.S. citizens.

Chiapas was one of the states newly included in this advisory, with the U.S. State Department in the area saying, “U.S. government personnel must remain in tourist areas and are not allowed to use public transportation.”

The warning also included states covering popular tourist destinations such as Cancun, Playa del Carmen, and Cozumel.

There are more than two dozen Mexican states now under the travel advisory.
